Be it known that I, VICTOR PLANcnoN, a citizen of the Frencl1 Republ1c, residing at Apparatus for t e Manufacture 'of Collodion Filaments, of which the following is a specification.

The present invention relates to improvements In a paratus for the manufacture of ment of its contact with the coagulating liqcollodion aments and the object isto allow uid are not superposed on each other. These of simultaneously producing the filament and of coiling it for the pur ose of producing regular cocoons, which a low of carrying out spirals overlap each other in the manner illustrated in Fig. 3 and after a certain length of time form a hollow, conical structure, as shown in Fig. 2. When this structure nearly fills the sieve-bottomed receptacle the latter is removed and replaced by a similar rece tacle of the same kind. The filament can e very easily wound, being. perfectly continuous and arranged in t e manner of regular, overlapping rings. The length of the filament is only restricted by the capacity of the receptacle, and may attain several thousand meters without a joint.

he apparatus described is very easy to control. When the horizontal pulley has been started, and an empty sieve-bottomed receptacle has been placed liquid, the 0 eration can be started. by turnii which controls the flow of the c diodion solution.

The collodion filament c linder g does not become dry but is merely slightly expanded and hardened. It enters the vessel 1' in a erfectly cylindrical state. The vessel 1 may e an ordinarybowl or the to evaporation. The apparatus may be constructed of any suitable material, and the dimensions and details of construction may be varied indefinitely. In all cases, however, the collodion filament traverses by gravity a certain vertical distance before coming into contact with th lating agent, and descends on to a rotating sieve, so that it forms thereon a regular coil similar easy to unwind.
